' 3 Claims. (c1. 8-155) This invention relates to machines and methods or processes of applying liquid to yarn while in the form of packages such as on bobbins. cones, spools or cops especially for setting the twist in the yarn.

It has been customary to apply the liquid to such yarn while the bobbins are travelling on a conveyor belt, or chain or through a revolving cylinder. A great difliculty in all of such machines has been the excessive wear on the moving parts. which operate without lubrication under the spray of water and penetrant. In some cases steam is applied but this is injurious to the bobbins and a steam room takes up a great deal of space. 0'

This invention is the result of extensive study of the conditions involvedin this work. Oneobject is to provide a satisfactory method. of uniformly applying the proper amount of liquid.

A special object is to provide a simple and inexpensive machine in which the packages re-. quire no moving devices to carry them through.

Another objectista provide a compact and inexpensive machine,

Accordingly one form of machine embodies a casing having a vertical series of inclined baifles arranged so that packages dropped on the upper baflle roll or spin down on to the next andthence over a grille and out of the machine. Sprays of the desired liquid are blown or otherwise forced from opposite sides of the machine onlto the moving packages. Excess of liquid is,thrown on by the impact upon th bailies and screen. The used liquid passes through the grille and back into the supply tank from which it is again forced from the spray heads to be used again until exhausted. This used liquid is preferably filtered before passing back intqthe supply tank.

Another form of machine employs a series of inclined grill sections down which the packages are allowed to fall freely while they are sprayed from at least one side with the desired liquid.

In still a third form the packages are dropped through a hopper. into a casing where they are deflected on to an annular platform and as they fall liquid is sprayed laterally from the center so that the rolling and twisting packages are moistened before they reach the platform. This platform may be rotated to assist in ejecting the. packages.

Fig. 1 is a front view of the novel parts of one form of machine for carrying out the invention.

F18. 2 is a vertical sectional view of the same.

Fig. 3 is a vertical sectional view of another form of machine.

Figs. 4' and 5 are vertical and horizontal sectional views respectively of another form of machine.

Th casing 5 may be of any suitable material and contains the shelves or bailles 6, I and 8 which may be arranged to overlap in a vertical series between the entrance 9 and the outlet Ill. The packages III will roll or fall from shelf to shelf however even if they do not overlap. A grille II is detachably mounted between the bafiie 8 and the outlet and serves to deflect thefalling packages to the outlet and the container l2.

The treating liquid is forced by a suitable pump and air pressure or other means (not. shown) from spray heads or nozzles H and I5 arranged respectively opposite the spaces between baflles 6 and I and between baflies l and}, respectively.

In this way as the packages roll'and spin back.

and forth, the .liquid is sprayed upon all sides. As the packages. strike against the bailies and the walls of the casing. the excessof liquid is thrown oil. by the impact 'so that the yarn is moistened uniformlyl- The unabsorbed liquid drains back intothe tank It preferably through the fllter n.

The filter or screen I! is preferably detachably ,mounted in. the casing and may be reached through the.'ilnor l8. Theliquid may be drawn.

from the pipe'f l andfdrced ,by a pump'.or,;ot l:ler means (not shown) throughthe nozzles Mfand l5 as above mentioned.

In the form shown in Fig. 3 there are aiseries of shelves or baiiies 20, 2|, 22 and 23 between the inlet 24 and the outlet 25 so that the bobbins or other packages roll, spin and twist from shelf to shelf while they are sprayed laterally from the heads 26 and 21. Part or all or each shelf such as 2|, 22 and 23 is perforated so as to allow excess liquid to return'tp the tank 28 from which it is returned to the spraying, means.

In the form she in fijigsgeand 5 there is a cylindrical casing o with a reed hopper 3| at the a top and a tank 32 at thebottom. Inside the'casing is a platform 33 which is perforated to allow liquid to pass through. In the center is a spray device having means 34 for spraying liquid laterallyaround the casing beneath the deflector 35. The pump 36 may' be located in the center bene ath the spraying device and surrounded by the cylinder 31. The platto'rm 33 may be revolved so as to bring the packages which fall upon it around to the discharge outlet 38 where they are deflected outwardly by the stationary plate 39. A filter 40 may be provided above the tank so as to keep the liquid free of foreign particles.

The successive shelves or plates serve to slow up the packages so that their speed is controlled to substantially that due to gravity acting from shelf to shelf rather than acquiring the momenand between inclined spaced perforated plates whereby for portions of their travel said spools fall free of said plates and subjecting said spools to a continuous spray during their movement along, over and between said plates to saturate thoroughly the yar'n on said spools.

2. The method of conditioning yarn on spools V or the like which consists in feeding the spools to the top of a vertical housing, permitting said spools to fall downwardly by gravity along a circuitous path over and between alternately inclined spaced perforated plates whereby for portions of their travel at different intervals said spools fall freeof said plates, subjecting said spools to a continuous spray from both sides of said housing during their movement along, over and between said plates to saturate thoroughly the yarn on said spools and finally draining said spools to remove the excess liquid therefrom.

3. The method of conditioning yarn on spools and the like which consists of feeding said spools to the top of a housing, permitting said spools to fall by gravity over a series of plates alternately inclined with a space between said plates whereby said spools are subjected to a tumbling action during their downward movement and subjecting said moving spools'to a continuous spray of liquid during their-downward travel out of contact with the plates whereby the yarn on said spools be- 20 comes thoroughly saturated.
